127 Claims.

This invention relates to machines for operating on shoes, and is herein illustrated as embodied in a machine having means for lasting a portion of a shoe, and means for thereafter epplying pressure and heat to the margin of the upper lasted inwardly over the shoe bottom and secured adhesively in lasted position. More particularly, the machine herein shown as an illustrative embodiment of the invention is constructed for operation upon a shoe the toe-end portion and the waist or shank portion of which have already been lasted, and is provided with means for lasting the shoe from the toe portion rearwardly as far as the previously lasted waist or shank portion and with pressing or ironing means for thereafter subjecting the margin of the upper throughout the length of the forepart to pressure and heat. It is to beunderstood, however, that the invention is not limited to a machine which'operates upon, or is confined to operation upon, that particular portion of a shoe; and in various novel aspects, moreover, it is not limited to an organization which includes both lasting means and pressing or-ironing means.

In themanufacture of shoes it is sometimes advantageous, especially when adhesive is used to secure the uppers'in lasted relation to insoles, to apply pressure and heat to the margin of the upper overlying the insole after the lasting op- 30 eration. In this manner the margin of the upper is pressed more firmly into adhering relation to the insole and the drying or setting of the adhesive is accelerated. Such application of pressure and heat, moreover, serves to eliminate any Wrinkles that there may be in the margin of the .upper and to provide an even surface for the reception of the outsole. Various features of the present invention are to be recognized in a novel organization of lasting means and pressing or ironing means whereby the'lasting operation may be performed and immediately thereafter the margin of the upper may be conveniently subjected to such pressure and heat. For the purposes in view, the machine herein shown is provided with a shoe support whereby each shoe may be readily presented in proper relation to the means that operates thereon, means for lasting' the iorepart of the shoe at the rear of the toe portion, and a pressing or ironing device mounted for movement from an idle position to afdefinitely determined position opposite the bottom of the shoe prior to its operation on the shoe.

More particularly, in the construction shown the arrangement is such that the shoe is positioned f bottom upward with its toe end pointing toward the rear of the machine, and the pressing device is mounted for forward swinging movement about a horizontal axis from an idle position nearer the rear of the machine than the shoe to a position over the bottom of the forepart of 5 the shoe. Conveniently, and in order to insure against danger of applying excessive heat to the shoe, there is provided means for heating the pressing device only when it is in its idle position, the construction shown comprising a 10 heater which is maintained yieldingly in contact with the device in that position and out of contact with which the device is carried in its movement into position over the shoe bottom. As above suggested, the pressing device of the illus- 15 trative machine is so constructed as to operate upon the margin of the upper throughout the length of the forepart, including the previously lasted toe portion, which is especially advantageous if the toe portion of the upper has been 20 secured adhesively to the insole; although it is to be understood that the beneficial efiect of the pressure and heat in pressing the margin of the upper smoothly upon the insole is not dependent upon the previous lasting of the upper with ad- 25 hesive. For better insurance that the upper will be secured tightly about the edge of the insole and will be ironed smoothly upon the insole, the pressing device, as shown, operates with an inward wiping action on the margin. of the upper at the opposite sides of the shoe bottom.

.The invention further provides novel means whereby parts of the machine are operated by fluid pressure, the construction disclosed being such that fluid, preferably oil, maintained under predetermined pressure by a continuously operating pump, is utilized at the will of the operator to vforce the shoe against a holddown for controlling it in the lasting operation, to eifect in part the operation of the lasting means, and thereafter to force the shoe against the pressing or ironing means. As further illustrated, mechanism is provided whereby the operator forces the shoe into contact with the holddown, and later into contact with the pressing means, prior to the action of the fluid pressure means to force the shoe more firmly against these parts.

Various features of the invention are further to be recognized in novel means for lasting the shoe. In the construction shown the upper is conformed to the contour'of the forepart of the last by a flexible elastic apron which is stretched heightwise of the last by the above-mentioned fluid pressure means, and the margin of the upper is laid inwardly over an insole on the last by means which acts through the apron and is conformable to the contour of the shoe bottom, this means, as illustrated, comprising at each side of the shoe a flexible cable arranged to extend lengthwise along the edge of the shoe bottom. As

.herein shown, each cable is operated by a treadle relatively to it by contact of the apron therewith and relatively to which the cable is movable lengthwise. As further illustrated, the apron is forced or wedged by the cable into a space provided between the shoe bottom and a member which is located opposite the shoe bottom and acts as a deflector to increase the pressure of the cable and apron on the margin of the upper. In order further to prevent undue wear on the apron, and also to facilitate forcing the apron inwardly over the shoe bottom, mechanism is provided for causing the fluid pressure means to relieve the pull on the apron, this mechanism, as illustrated, being operated in response to force applied to the treadle after the apron has been forced far enough inwardly to insure against loss of control of the upper. The cable which operates at each side of the shoe bottom is maintained initially in anout of the way position and is carried inwardly to position it partially around the apron before the cableis operated as above described; and to avoid interference between the parts which operate at the opposite sides of the shoe bottom the construction disclosed is further such that the overlaying operation is performed on the margin of the upper first at one side of the shoe bottom and thereafter at the other side of the shoe bottom. I

'Still other features of the invention are to be recognized in novel shoe-pressing means. In accordance with one feature, the invention provides novel pressing or ironing means movable inwardly over the "shoe bottom in wiping contact therewithand conformable to the contour of the shoe in response to pressure of the shoe thereon. In the construction shown such means comprises shoe-engaging plates which are flexibly conformable to the contour of the shoe, the plates being movable inwardly toward each other at the opposite sides of the shoe bottom in response to pressure of the shoe upon them. As further illus-- trated, two pairs of plates are thus provided, the two plates of each pair being arranged in superposed relation a d having slits therein to increase their flexi ility. In accordance with a further feature, shoe-pressing means which is conformable to the contour of the shoe is yet so controlled as to apply firm pressure to the shoe after its conformity to the shoe contour. For this purpose, in the construction herein shown, the flexible plates that operate at each side of the shoe bottom are backed up by a group of loose metal balls which adjust themselves to the con tour of the shoe with the plates and thereafter become substantially fixed relatively to means which controls them so that theyrender theplates eifective to apply firm pressure to the shoe. For confining each group of balls laterally the construction shown further comprises a rowof pins which act as a fence around the balls and are yieldable in response to pressure of the plates thereon. It will be recognized that means other than metal balls may be utilized, if desired, for

the purpose in view. While the above-mentioned plates are heated by the means hereinbefore referred to, it is to be understood that in its provision of shoe-pressing means the invention is not limited to a construction for applying heat as well as pressure, since under some conditions there may be desirable advantages in the use of pressure alone, and further that the invention is not limited to means for applying pressure on the particular portion or surface of the shoe illustrated.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described'by reference to the accompanying drawings and pointed out in the claims.

The machine herein shown is a twin machine having two sets of operating instrumentalities arranged side by side for operating respectively on shoes in different locations in the machine. The

two sets of instrumentalities may thus be con- 6 veniently used to operate respectively on right and left shoes, and conveniently also the lasting operation may be performed on a shoe by one set of instrumentalities while a previously lasted shoe is maintained under pressure of the ironing means by the other set of instrumentalities. Since the two sets are constructed substantially alike except for such differences as are required by their difierentv locations, and since they are operated and controlled independently of each 2,085,468 other; the present description will be confined spindle hole and a shoe rest I2, conveniently referred to hereinafter as a toe rest, which underlies the forepart of the shoe. The toe rest is hollowed out laterally to receive the shoe, as illustrated in Figs. 13 and 14, and comprises a rubber pad I4 mounted on a block I6 fast on the head I8 of a stud ,26 (Fig. 9) which extends downwardly into anopening in a holder 22. The stud is not fast in theopening, so that the toe rest may turn and adjust itself to the shoe. The holder 22 is mounted to swing in directions lengthwise of the shoe on a rod 24' which ,is

mounted in a plate'26 secured by a serew 28 (Fig. 6) to a bar 36 extending lengthwise of the shoe. As shown in Fig. 9, the left-hand portion of the rod 24 is of greater diameter than the portion which extends through the plate 26 and this enlarged portion abuts against one side of the plate. Rotatably mounted on the rod at the other side of the plate 26 is a sleeve 32 abutting at one end against the plate and threaded exteriorly to engage corresponding threads formed in a downturned portion of the holder 22, this sleeve having a knurled head 34 thereon for turning it. A washer 36 and a nut 38 mounted on a still further reduced portion of the rod 24 serve to confine the sleeve 32 on the rod and to hold the rod in place in the plate 26. It will be unde stood that by turning the sleeve 32 the holder 2 and theme rest I2 thereon may be adjusted in directions widthwise of the shoe. A spring-pressed plunger 46 (Fig. 6) mounted in a socket in the holder 22 and engaging the top face of the plate 26 tends to swing the toe rest in a direction toward the heel end of the shoe, and cooperating with the spring to determine adjustably the position of the toe rest lengthwise of the shoe is a screw 42 threaded in a lug on the holder 22 and engaging the top of the'plate. 26. It will thus be seen that the toe rest may'f'r'eadily be adjusted in directions both lengthwise and laterally of the shoe as required-by shoes of different sizes or styles.

The heel pin I6 is secured to a slide 44 (Figs. 6, 10 and 11) adjustably movable in directions widthwise of the shoe along guideways formed in a holder 46. Formed on one side of the slide 44 are teeth 48. arranged to be engaged by similar teeth formed on a detent member 56 which extends through anopening in the holder 46.

The member 56 is pivotally mounted on a screw 52 threaded in the holder 46 and is provided with a handle 64 by which it may be swung against the resistance of a torsion spring 56 to release the slide 44 and permit the adjustment of the slide. As illustrated, the slide is in a position in which the last pin I6 is laterally offset to the right of a vertical plane extending from front to rear centrally through the toe rest I2 so as to position a right shoe with the longitudinal median line of the forepart of the shoe bottom lying substantially in that plane. It will be understood that for positioning a left shoe for the operation of the left-hand set of instrumentalities the last pin will be laterally ofiset in the opposite direction, as illustrated at the left-hand side of Fig. 1. The holder 46 is mounted for swinging movements in directions lengthwise of the shoe on 1 proximately at the bottom face a direction away from the toe rest, and cooperating with the spring to determine adjustably the position of the pin is a screw 68 threaded in the rflder 46 and engaging at its lower end the. slide "The bar 36 is fastened on the top of a holder lengthwise of the shoe about an axis located ap- .of the ball portion of the shoe. This segmental portion of the holder I6 is mounted on a correspondingly curved support I2 (Figs. 16 and 12) and is confined thereon by a plate I4 fast on the support. The support I2 has a depending sleeve I6 which is fast on the upper end of a rod 18 mounted for vertical movements in upper and lower bearings in the frame of the machine, the sleeve I6 resting initially on an arm 86 of the frame, as shown in Fig. 6, with the work support in a lowered position. The holder I6 and the parts supported in a lug 66 formed on a slide whichhas a lower segmentalportion curved supported thereon are adjustable along the' curved guideway on the support I2 about the previously mentioned axis to position the bottom of the forepart of the shoe in the proper plane parallel to the lower face of a holddown plate 82 which is supported as hereinafter described. To facilitate such adjustment of the holder l6 there is fast on the front end of the bar 36 a handle 84. The holder is maintained in adjusted position by a spring-pressed pin 85 (Fig. 12) slidingly mounted in a thimble 88 in the support I2 and arranged to enter any one of a number of holes 66 provided in one side of the segmental portion of the holder 16'. The inner end of the thimble 88 lies in a curved slot 92 (Figs. 6 and 10) formed in the side of the holder 16 to assist in confining the holder on its guideway on the support I2.- When it is desired to adjust the holder the operator pulls the pin 86 outwardly by engaging a head 94 (Fig. 12) on the pin.

As above suggested, the slide 62 which carries I the last pin I6 is movable along the bar 36 to position the last pin in proper relation to the toe rest for shoes of different lengths. To hold the slide in the position to which it is thus moved there-are formed on the lower edge of the plate 64 which is fast on the slide a series of teeth 96 (Fig. 6). engaged by similar teeth on the upper end of a detent 98 which is slidingly movable upwardly and downwardly in a guideway in the holder I6 and is confined by a plate I66 fast on the holder. A pin I6I' projecting from the detent into an enlarged opening in the plate I66 limits downward movement of the detent. At its lower end the detent 88 has an extension I62 provided with a lower face curved about the same axis as the segmental portion of the holder I6 and engaging a similarly curved upper face of a segment I64 provided with adepending portion I66 which is vertically movable in a guideway. formed in an oifset portion of the plate I4. A light spring I68 mounted in a socket in the holder 16 and engaging the extension I62 of the detent 98 I4 and engagingapin II2 which is in the proper lengthwise position there is pro of the segment I04 tends to force this segment downwardly. It will thus be seen that when permitted the springs I08 and IIO will cause the detent 98 to release the slide 62 and thus permit the operator to move the slide along the bar 30. To maintain the detent in position to hold the slide 62 against movement along the bar 30 the pin H2 is upraised by a bell-crank lever II4 one arm of which underlies the pin and is controlled by a spring II6 of sufficient strength to overcome the two light springs I08 and I I0, The bellcrank lever H4 is pivoted at II8 on a short arm I20 of a lever I22 which is pivoted at I24 on the depending sleeve portion I6 of the support I2 and isutilized for a purpose hereinafter described, the spring II6' being mounted in a socket in the arm I20. The bell-crank lever H4 is connected by a link I26 (Fig. 2) to a handle I28 pivoted at I30 on a depending lug on the lever I22. It will thus be seen that when the operator raises the handle I28 the latter acts through the link I26 to swing the bell-crank lever I I4 against the resistance of the spring I I6 and thus to permit the pin II2 to move downwardly so that the spring I08 forces the detent 98 away from the teeth on the plate 64. After the operator has moved the slide 62 to the desired position he releases the handle I28, whereupon the spring II6 forces the detent again into locking relation to the slide.. It will be evident that the segment I04 maintains its controlling relation to the detent 98 in all positions ofadjustment of the holder- 10 along its curved guideway in the support I2.

Since the locations of the spindle holes in the position substantiallyat the'forward end of the,

bar 30 to receive each last and shoe. The operator will then move the slide with the shoe toward the toe rest to present the shoe in proper position, holding the handle I28 upraised so that the slide is unlocked to permit this to be done. To assist the operator in determining when the shoe vided a gage I32 (Figs. 6 and 8) the forward end of whichis arranged ,tO indicate the proper lengthwise position of the shoe by reference to the ball line 'of the shoe. The gage I32 is located somewhat above the shoe bottom at the time of presentation of thework, as indicated in Fig. 6,

' ,but isso arranged in relation to the operators 4 line of vision as he stands in front of the machine that it enab1es him to determine by sight with 'sufiicient accuracy when the shoe is properly position'ed. As will be evident hereinafter; the character of the means provided for operating on the shoe is such as not to require 'thatthe shoe be positioned either lengthwise or laterally with a very high degree cf accuracy. The gage I32 is supported by a plate I34 which is spaced a substantial distanbe above the previously mentioned holddown plate 82 for a purpose hereinafter described. Both plates 82 and I34 are supported on the forward end of an arm I36 mounted as also hereinafter described, and the plate I34 is confined between a shoulder on the arm and a shoulder-on a member I38 on the lower end of which the plate 82 is secured (Fig. 13) The'member I38 has an upwardly extending hollow stem I40 mounted in an opening in the arm. I36 and fastened to the arm by a nut I42, the member I38 being held from turning by a pm In (Fig. 6)

which projects from the arm I36 into a slot I 46 in the stem I40. Within this hollow stem is a rod I48 on the upper end of which is mounted a handle I50 for use in controlling the arm I36 in a manner hereinafterexplained. The gage I32 is supported on the plate I34 by means of another plate I52 which rests on the plate I34 and is pivoted for swinging movements laterally of the shoe on a screw I54. Fast on the forward end of the plate I52 is a pin I56 on the lower 'end of which the gage I32 is secured, this pin extending through a slot I58 in the plate I344. This slot is wide enough to, permit some swinging movement laterally of the shoe of the plate I52 and the gage I32 to afiord'suflicient room for the laying of the margin of the upper inwardly over the shoe bottom, first at one side and then at the other side of the shoe bottom, as hereinafter described.

After the operator has presented the work in the manner above explained he raises the work at its lower end and connected to a wedge member I62 by means of pins I64 which project from the forked arm into vertical slots I66 in the opposite sides of the wedge member. The wedge member I62 is slidable along guideways provided in a block I68 mounted as hereinafter described and in which the work support rod I8 is slidingly mov able, and in engagement with the upper face of the wedge member is a collar fast on the rod I8. It will thus be seen that by depression of the hand lever I22 the wedge member I62 is forced inwardly between the block I68 and the collar I'I0 andthereby serves to force the work support upwardly to bring the bottom of the shoe into engagement with the holddown plate 82. Since the hand lever I22 is pivotally mounted, as hereinbefore described, on a part of the vertically movable work support, the guideways on the block I68 are upwardly inclined so that the wedge member I62 receives some'upward movement as it is operated to raise the work support. After the operator has raised the work support by depreshas thereon a lug I12 (Fig. 6). extending rearwardly therefrom'between opposite guiding faces,

one of which is shown at II4,on a bracket I I on the frame of the. machine.

As hereinbefore suggested, the machine herein shown is designed to operate upon a shoe which has already been lasted at the toe-end portion and at the waist or shank portion, and is provided with meansfor lasting the forepart of the shoe between these previously lasted portions. This means comprises a flexible lasting apron II6 arranged to extend across the top of the forepart of the shoe betweenpthe shoe and the toe rest I2 and also to extend upwardly at both sides of the forepart, the apron preferably consisting of a sheet of rubber molded to provide a hollow to receive the shoe. As shown in Fig. 6, the apron has a stem I'II thereon which extends into av hole in the toe rest pad I4 to fix its position relatively to the toe rest. The apron may, as shown, extend about the toe portion of the shoe as well as about the forepart at the rear of the toe, and

it preferably is of suflicient length to overlap more or less previously lasted portions of the upper at the'waist of the shoe. Theapron I18 overlies ,the toe rest I2 at all times andis therefore engaged by the shoe when the operator presents the work to the machine. Through this apron, moreover, pressure is applied to the top of the forepart of the shoe by the toe rest when the shoe is clamped against the holddown plate 82,

the toe rest extending far" enough toward the heel end of the shoe to conform the top of the forepart of the upper at the rear of the toe to the contour of the top face of the last which is more or less concave lengthwise of the last in that location. The opposite side edges of the apron I18 are clamped between plates I18 (Figs.

13 and 14), and in these plates are openings I80 rods- I88 mounted for upward and downward movements in bearings formed in lugs I88 and I80 on the bracket 115. These bearings, it will be seen, are so arranged that the rods I88 are inclined upwardly and forwardly toward the front of the machine. To conform the forepart of the upper tightly to the last atrthe rear of the toe portion the apron I18 isstretched bylupward movement of the rods I88 'in such forwardly inclined directions, in the course of which upward movements the arms I84 are permitted to turn about the upper ends of the-rods so that they assume positions determined by the action of When the apron is the rubber apron thereon.- thus stretched the portion thereof at each side of the shoe is inclined somewhat outwardly from the side of the shoe as indicated at the left-hand side of Fig. 13.

= The upward movements of the rods I88 to stretch the apron I18 as above de'scribedare effected by power through the action of fluidpressure means. For this purpose each rod I88-has fast thereon a collar I92 (Figs. 1 and 6) to which there is pivotally connected an operating link I84. 'The right-hand link I94 is connected to an arm I88 (Fig. 2) which is fast on a rock shaft I08 mounted in bearings in the frame, and the left-hand. link (Fi 1) is connected to an arm 200 also" fast on-this rock shaft. The arm 200 has integral 'therewitha downwardly curved arm 202 which is pivotally connected to the upper closed end of a cylinder 204'. This cylinder is slidable upwardly and downwardly on a piston a 208 (Fig; 3) which has therein a central bore-208 curved seat formed at the bottom of a tank or' communicating at its lower end with a transverse passage 2I0. 'At its lower end the piston 208 has a curved face 2I2 resting on a correspondingly I reservoir 2-I4 which is partially filled with liquid,

preferab'y oil. as illustrated in Fig. 2. It will 'thus'be seen that the piston 208 may swing latorally in the upward and downward movements of the cylinder 204 as required by the connection of the cylinder with the lever arm 202. A stop screw 2 I8 engages one side of the lower end por- ..tion of the piston 208 to hold it against lateral displacement, and extending into the passage 2I0 at the opposite side of the with the pipe 2I 8 is atelesccpic pipe 228 which piston is a pipe 2I8' about which the piston swings. Communicating leads upwardly to a short horizontal pipe 222 (Fig. 4) leading intoan opening 224 (Fig. 5) in a valve unit 228 by which the flow of oil to the piston 208 is controlled. Oil is supplied under pressure by a gear pump. 228 (Fig.4) driven continuously through a belt 229 by an electric motor 230, the oil being drawn from the tank 2I4 through a pipe 232 leading to the pump and being discharged from the pump through a pipe 234; The pipe 234 discharges the oil into a passage 238 communicating with another passage 238 which leads into the valve unit 228. The oil takes a course indicated by the arrows on Fig. 5 toward the upper face of an inlet valve 240 arranged to cooperate with a valve seat 242, this valve having a depending stem 244 slidingly mounted in a bore formed in an upwardly ex tending hollow stem 248 of another valve 248 arranged to cooperate with a valve seat 250 around an outlet at the lower end of the unit 238. A light spring 252 in the hollow stem 248 tends to force the valve 240 upwardly and the valve 248 downwardly. The valve 240 is opened by pressure of the oil against it when permitted by valve-controlling means hereinafter described,

at which time the valve 248 is closed so that the oil under pressure passes through the opening 224 and into the hollow piston 208. The oil therefore acts to raise the cylinder 204 and thereby to operate the lasting apron I18 in the manner hereinbefore described. In order to limit the stretching of the apron, there is a pressure control valve 254 (Fig. 4) cooperating with a valve seat258in avalve casing 258 to control a by-pass tuming the member 282. The apron I 18 will accordingly be stretched until its resistance to the movement of the cylinder 204 is greater than the resistance of the spring 284 to the opening of the valve 254, whereupon the valve will open and permit the oil to circulate. Thereafter the apron will beheld stretched under the force thus predetermined until such time as the valve 240 is closed and the valve 248 is opened, whereupon the oil is permitted to escape from the cylinder 204 post the valve 248 and int the tank 2 and the parts which operate the apron I18 return to their starting positions. It will be understood that the oil circulates through the by-pass 259 at all times when the valve 240 is closed.

The valves 240 and 248 are controlled by a lever 288 (Figs. 4, 5 and 7) pivotally mounted on an arm 288 of the valve unit 228 and arranged to engage the lower end of a rod 210 extending downwardly from the .valve 248. The lever 288 is connected by a link212 to one arm of a bellcrank lever 214 pivoted on aQrod 218 on the frame of the machine, the other arm of this bellcrank lever being connected by a link 218 toa lever 280 pivotally mounted on a rod 282 on the frame. Connectd to the lever 280 is a link 284 provided with a slot 288 into which projects a pin 288 carried-by atreadle 290 about a rock shaft 292 at the base of the machine, the 'treadle being held in its normally upraised position by a spring 294. When the treadle is in mounted to swing 248'to be closed by the combined action of the spring 252, of gravity and of the pressure of the oil and permitting the valve 246 to be opened by such pressure. Such movements of the valves occur at the beginning of the downward movement of the treadle and result in the stretching of the lasting apron I16 in the manner hereinbefore described, after which the treadle is further depressued for another purpose as will be explained. It will be understood that when the treadle is released by the operator it acts in its return to starting position to close the valve 246 and open the valve 248 and thus to permit the apron and the parts which control it to return to their starting positions.

It is desirable that during the lasting operation the shoe be pressed against'the holddown plate 82 more firmly than the operator can conveniently press it by means of the hand lever I22, and accordingly fluid pressure means also controlled by the depression of the treadle 296 is provided for forcing the work support in an upward direction. For this purpose there are pivotally mounted on a rod 296 (Figs. 1 and 2) at the front of the frame of the machine two levers 298 and 366 which are-connected to opposite sides of the block I68 in such manner as to raise this block when the levers are swung upwardly. It will be understood that when the block I68 is thus raised it acts through the wedge member I62 to raise the shoe support rod 18 and the parts thereon. At their rear ends the levers 298 and 366 are pivotally connected to a cylinder 362 within which is a hollow piston 364 mounted at its lower end to rock in a bearing in the tank 2 in the same manner as the .previously describedpiston 266 (Fig. 3). The cylinder 362 and the piston 364 and the partsv associated therewith are, in fact, constructed for the most part substantially like the parts shownin Fig. 3 for operating the lasting apron, and accordingly the construction is not illustrated in detail. The oil is conducted to the lower end of the piston 364 through a pipe 366 (Figs. 2 and. 4) leading from a valve unit 368 of substantially the same construction as-the valve unit 226 previously described andshown in Fig. 5. The 'valve unit 368 communicates through a passage 369 (Fig; 4) withthe passage 236 leading from the pump. It will be understood that in this valve unit there is an inlet valve similar to the valve 246 shown in Fig. 5, and an outlet valve, similar to the valve 248, controlling a passage leading from the valve unit back to the tank 2I4.' These valves are controlled by a lever 3I6 (Figs. 2, 4 and '7) which is connected by a link 3I2 to one arm of a bellcrank lever 3I4 pivoted on a rod 3I 5 on the frame. A spring 3I6 connected to this bell-crank lever tends to depress the link 3I2 and thereby maintains the lower outlet valve in the valve unit 368 in open position and the upper inlet valve in closed position. Swiveled on one arm of the bellcrank lever 3I4 is a block 3I8 in which there is slidingly mounted a rod 326 connected at itslower end to one arm of a bell-crank lever 322 pivotally mounted on the previously mentioned rod 216.

-gages the apron.

Mounted on the rod 326 is a sleeve 324 the upper end of which is arranged to engage the block 3 I6 and the lower end of which. issuppo'rted on a nut 326 (Fig. 2) on the rod. It will thus be seen that when the rod 326 is raised by the bell-crank lever 322 it acts through the sleeve 324 to operate the bell-crank lever 3I4 and thereby to raise the link 3I2 to cause the valve at thelower end of the valve unit 368 to close and the upper valve to open, whereupon the cylinder 362 is operated to raise the shoe support in a manner which will be readily understood from the previous description of the means for operating the lasting apron, the amount of'force applied to the shoe support being determined by the pressure control valve 254 (Fig. 4).

For operating the bell-crank lever 322 there is connected to one arm of the lever a link 328 (Fig. '7) which is also connected to an arm 336 pivoted on the rod 282, and pivoted to this arm is a link 332 provided with a slot 334 into which extends the previously mentioned pin 288 carried by the treadle 296. The spring 3I6 acts through the link 3I2 and the lever 3I6 to hold the valve at the lower end of the valve unit 368 normally open and the upper valve. closed, as previously fore, when the treadle is depressed, it is necessary to operate the bell-crank lever 3I4 against the resistance of the spring 3 I 6, and for this purpose there is connected to the link 332 a comparatively strong spring 336 which is also connected to the treadle and acts upon depression of the treadle to pull the, link downwardly and thus to elevate the rearwardly extending arm of the bell-crank lever 3| 4 through the action of the sleeve 324 on the block 3I8. 11-. will be evident that the fluid pressure means for forcing the shoe support upwardly-is thus rendered effective early in the depression of the treadle 296 at substantially the same time when the fluid pressure means pre-- viously described for operating the lasting apron is rendered efiective on the apron.

After the shoe support has-been forced upwardly and the lasting apron hasbeen stretched as above described to conform the unlasted portion of the forepart of the upper to the contour of the last, 'it is necessary to lay the margin of this portion of the upper inwardly over the insole into position to be secured to the insole by cement previously applied to the margin of the upper materials or to the insole. For this purpose there are provided two flexible cables 338 (Figs. 4 and 6) which extend'lengthwise along the edge of the shoe bottom and act through the 'apron I16 at the opposite sides of the shoe respectively to lay the margin of the upper over the insole and press it upon the insole, as illustrated with reference to one side of the shoe in Figs. 13 and 14. These cables may be made,

"for example, of twisted strands of flexible metal,

and as illustrated the portion or each cable which acts on the lasting apron extends through a coil spring 346 which loosely surrounds it and en- The spring may turn more or less on the cable in response to the frictional action of the apron thereon in laying the. upper over the insole, and as the cable is pulled as hereinafter described it slides lengthwise relatively I to parts of the spring which 'are in contact with the apron. The spring thus facilitates movement of the apron by the cable and lessens the wear on the apron. Each cable 338 at its for-- ward end is connected to a block 3 (Fig. 6) swiveled on an arm 342 fast on a stud 344 (Fig. 2) which is mounted to turn in a hand lever 346, and connected to the lower end of this stud is a torsion spring 348 which tends to hold the arm 342 outward against a pin 358 (Fig. 4) on the lever 346. Each lever 346 is mounted for swinging movements laterally of the shoe on an arm of the previously mentioned bracket I and also for limited lengthwise movement relatively to a bolt 352 which extends througha slot 354 (Fig. '4) in the lever and has a head 356 with straight sides extending lengthwise of thelever in a guideway in the lever. The bolt 352 is mounted to turn in the arm of the bracket I15 as the lever 346 is swung inwardly to carry the cable 338 toward the lasting apron I16, and when the lever has been swung inwardly far enough 314 which at its lower end is pivotally connected to carry its rear end outwardly beyond a lug 358 (Fig. 4) on the bracket I15 the operator pushes the lever lengthwise toward the rear of the machine as far as permitted by the bolt 352 and the slot 354 to engage an inner face 368 on the rear end of the lever with the outer face of the lug 358, so that the arm of the lever which carries the cable is locked against reverse outward swinging movement. When the lever 346 is in this position the cable 338 connected to it, which is further controlled as hereinafter described, is held inwardly against the lasting the toe end of the shoe. Each cable further ex- I tends over a grooved pulley 362 supported by a bracket-364 (Fig. 6) which rests on. the bracket I15 and has a depending stem 366 swiveled in an opening in this bracket so that the pulley with its supporting bracket 364 may turn about a vertical axis to adapt its position to the position of the cable. The cable extends downwardly through an opening in the stem 366 and is connected at its lower end to one arm of a bell-cranklever 368 (Fig. 2) pivotally mounted on a rod 318 on the frame. It will be understood that each cable is thus connected to a separate bell-crank lever 368, as shown in Fig. 1. The operation of each cable to lay the margin'of the upper inwardly over the insole is effected by swinging the bell-crank lever 368 connected thereto in the direction to pull downwardly on the lower end of the cable,-and this isaccomlished by further depression of the treadle 283 after its initial depression to cause the shoe to be clamped firmly against the holddown plate and the lasting apron to be stretched by the fluid-pressure means as hereinbefore described. For this purpose there is pivotally connected at 312 to 2. depending arm of each lever 368 a link by a stud 316 to one arm of a'bracket 318 (Fig. 7) pivoted by means of a rod 380 upon the rear end of the treadle 290. When the. treadle. is deforward movement of the link 382 pressed, therefore, both bell-crank levers 368 are swung thereby to pull downwardly on the lower ends of the cables 338 and thus to draw or pull the portions of the cables which are opposite the lasting apron I16 lengthwise and laterally of the shoe, the arms 342 which support the forward ends of the cables swinging toward each other about their connections with the levers 346 against the resistance of the springs 348 in response to the pull of the cables thereon. Since only one of the cables, however, has been carried inward against the apron by movement of its lever 346, as above explained, the other cable when operated by the treadle is ineffective upon the apron to lay the margin of the upper over the insole at that side of the shoe bottom. It will be understood that the pull applied to the cable which is effective on the apron tends to straighten the portion of the cable previously referred to as wrapped in a curve about that portion of the apron which is located at the begin ning of the waist portion of the shoe, while at the same time the arm 342 connected to that portion of the cable isswung by the pull of the cable thereon in a direction to carry the cable still farther inwardly over the shoe bottom. The apron is thus rendered effective to lay tightly inward over the insole that portion of the margin of the upper where the side of the last curves inwardly toward its waist portion, as well as the portions of the margin of the upper extending forwardly to the toe-end portion of the shoe. As illustrated in Figs. 13 and 14, the cable when thus operated acts to force or wedge the rubber apron inwardly between the shoe bottom and the previously mentioned plate I34, the plate having a beveled lower face and acting as an abutment or deflector to force the cable downwardly and thus to increase the pressure of the apron on the upper so as to render the apron more effective to draw the upper tightly inward over the edge of the insole and to press it firmly down upon the insole.

In order to facilitate the laying of the margin of the upper inwardly over the insole by each cable 338 through theoperation of the treadle, and to avoid undue' stretching of the rubber ap'ron I16 and also excessive inward strain of the apron on the margin of the upper such as might tend todisplace the margin of the insole,

there is further provided means for relieving the upward pull of the arms I84 on the apron by .closing the valve 240 and opening the valve 248 of the valve unit' 226 (Fig. 5) associated with the cylinder 284 (Fig. 3) which operates the apron. For this purpose there is connected to a depending arm of the lever 280 (Fig. '7) a link 382 provided with a slot 384 through which extends a pin 386 projecting from one of the studs 316. It will be understood that when the link 284 connected to the lever 286 is released by the pin 288 in the initial depression of the treadle -29!) as hereinbeforedescribed, the link 3.82 is moved far enough by the lever 280 to cause thepin 366 to lie at the forward or left-hand end of the slot 384 (Fig. 7) The valve 243 accordingly may thereafter be closed and the valve 248 opened by derived from movement of the pin 386. Such movement of the pin is effected by swinging the bracket 318 on the treadle about the axis of the rod 388, the swinging of the bracket resulting from the force applied thereto by the treadlc because of the factthat the pivotal connections 316 between the bracket and the lower ends of the links 314 are offset forwardly from straight lines extending from the rod 388 to the pivotal connections 312 (Fig. 2) between the upper ends of the links 314 and the bell-crank levers 368. The tendency.

of the force applied by the treadle accordingly is to swing forwardly the upwardly extending arms of the bracket 318, on one of which the pin 386 is mounted, and also the lower ends of the links 314. Such swinging movement of the bracket'is limited by studs 388 carried by'the links 314 and extending through slots 398 in the arms of the bracket, and is against the resistance of springs 392 which are adjustably connected to the links and to the arms of the bracket and hold the parts initially in the positions indicated in Fig. 7 with the studs 388 at the left-hand ends of the slots 398. These springs do not yield until after the apron I16 has been forced far enough inwardly to be gripped between the shoe bottom and the plate I34, as illustrated in Fig. 13, so as to insure against loss of control of theupperwhenthe pullon the apron is relieved. When the springs yield the valves are operated as described and the arms both the opposite side portions of the apron are thus lowered, although a cable is acting only at one side thereof. As the treadle is further de- 3 cause the apron again to be stretched upward by the arms I84, the operator maintaining the treadle far enough depressed to permit this action of the valves. This stretching of the apron assists in withdrawing the cable 338 from between the shoe bottom and theplate I34. Thereafter the lever 346 at the other side of the shoe is swung inwardly and locked and the treadle is again fully depressed to effect the overlaying of the margin of the upper in the same manner at that side of the shoe. The operator then fullyreleases the treadle, and in response to its return upward movement the valves controlling the fluid-pressure means which operate the lasting apron and the shoe support are returned to their starting position so that the sides of the lasting apron are dropped and the upward pressure of the shoe on the holddown plate 82 is relaxed. Thereafter the operator lifts the hand lever I22 to withdraw the wedge I62 and thereby permit the shoe to be lowered out of contact with the holddown plate preparatory to the ironing operation on the vforepart oi the shoe bottom.

By reference to Figs. 4 and 6 it will be seen that-the two cables 338 extend through 'a slot formed in a guide 394 having-rearwardly extending arms which are pivoted on a rod 396 mounted on a'hoider 398 fast on the bracket I ported at its forward end on the cables 338 when the parts are in their normal positions. Connected to an arm 482 which extends downwardly from the guide 394 and also'to the hub of one of the arms I84 which carry the lasting apron I18 is a spring 484 which is tensioned by the upward 1 movement of the arm -I84 to stretch the apron.

Through this spring therefore the guide 394 is swung upwardly at that time against the resistance of the light spring 480 and serves to lift the cables 338 so as to insure that when each cable is operated to lay the margin of the upper over the insole it will be located at the proper height to be pulled inwardly overthe shoe bottom.

The means for pressing or ironing the bottom of the forepart of the shoe after the lasting operation comprises a device supported on two bars 485 (Figs. 1 and 2) which are fastened at their lower ends to the previously mentioned rockshaft 292 on which the treadle 258 is loosely mounted, so that the device may be swung forwardly from an idle position to a position over the shoe bottom. By means of trunnions 488 (Fig. 16) the bars 486 support at their upper ends a casting 4! which is fast on the trunnions and by which two ironing units are supported as hereinafter described. In the ironing operation the casting 4I8 and the ironing units thereon may swing about the axis of the trunnions 488, i. e., an axis extending laterally of the shoe, for better conformity of the ironing units to the lengthwise contour of the shoe bottom. The' casting 4l8, however, is held normally in a predetermined position with respect to movement about this axis by springs 4I2 which are mounted in sockets in enlarged upper end portions of the bars 496 and press upwardly against lugs M4 on the casting, as shown in Figs. 2 and 15. On the front of the casting M8 is secured the arm I36 which supports the holddown plate 82 as-hereinbefore described. On the rear of the casting is secured an arm 4H3 in the rear end of which is threaded for upward or downward adjustment a stud M8 the lower end of which is in position to engage a plate .428 fast on the frame of the machine when the bars 488 are at the limit-of their rearward movement determined by engagement of the bars with studs 422 on the frame, one of these studs being shown in Fig. 2. By its engagement with the plate 428 the stud 8 serves to prevent any substantial tipping movement of the casting 4I8 about the axis of the trunnions 488 when the shoe is pressed up against the holddown plate 82, and. acts positively to hold this plate against the upward pressure of the shoe thereon. The plate 428, however, opposes no substantial resistance to the forward swinging movement of the casting 4I8 into position over the shoe bottom.

Within the casting 4IIl there is another casting 424 (Figs. 15 and 16) which is mounted on a rod 426 for swinging or tipping movements about an axis extending lengthwise of the shoepthis rod being secured at its ends to the casting 4I8. The'casting 424 is maintained normally in a predetermined position with respect to such tipping movement by springs 428 mountedin sockets in the castings M8 and 424. Supported on the casting 424 are the two ironing units arranged to act respectively at the. opposite sides of the shoe bottom and eachcomprising a holder-430 on which are secured by screws 432 a pair of flex j ible resilient ironing plates 434 (Fig. 18), these plates being arranged in superposed contiguous relation. Extending inwardly from one edge of each of theplates 434 in directions parallel to the direction of ironing movement of the plates are a plurality of slits 435 which divide the plate into a series of fingers 438, the slits in the differplate. By reason of this construction the plates are rendered more flexible to permit them toconform readily to the contour of the shoe bottom. At their ,outer edges, i. e. the edges that are farthest from the shoe, the two plates of each pair are embraced by a retainer 440 through which the screws 432 act to secure the plates to the holder 438. Near the inner edges of each pair of plates there are fastened to the lower plate angular clips 442 (Fig. 18) the upper.

end of each of which is arranged to extend into a slot 444 in the holder 43!) and over a ledge 446 on the holder to limit downward movement of the inner end portions of the plates. It will be understood that when the shoe is pressed against the ironing means the slots 444 permit the plates to yield upwardly: The plates 434 are arranged to act not only on that portion of the margin of the upper which is laid inwardly over the insole bythe lasting means, but also on the margin of the previously lasted toe portion of the upper, and preferably extend somewhat forwardly and rearwardly of the forepart of the shoe.

' Each holder 439 is suspended on the casting 424 by a pair of links 448 and 450 (Fig. 19) at the front of the casting and by another such pair of links (Fig. 15) at the rear of the casting. Each link 448 is pivotally mounted on a pin 452 on the casting 424 and is pivotally connected to the holder 438 by a pin 454. Each link 458 is pivotally mounted on a pin 456 on the casting and g is pivotally connected to the holder by a pin 458.

The two links 448 and 458 of each pair constitute, ineffect; parallel links, and it will be evident from Figs. 16 and 19 that the arrangement of the links is such thatin downward movements of the two holders 438 relatively to the casting 424 the. holders swing outwardly away from each other and in upward movements relatively to the casting they swing inwardly toward each other. The two holders are forced downward and outward by spring-pressed plungers 468 and 462 mounted in the casting 424, the movements of the holdersin these directions being limited by pins 464 extending into slots 465 in the holders as illustrated in Fig. 16. It will be understood that when the shoe is forced upwardly against the ironing plates 434' the plungers 460 and 462 yield, thus permitting the plates at the opposite sides of the shoe bottom to be forced inwardly toward each other with a wiping action on the overlasted margin of the 'upper in response to the pressure o1" the shoe on the plates. Such upward and inward movements of the holders 430 are positively limited by contact of the holders with the casting 424, as illustrated in Fig. 19.

It will be understood that when the shoe is pressed upwardly against the ironingplates 434 they are flexed by the pressure of the shoe thereon to conform to the contour of the shoe bottom, and that the castings 424'and 4| 8 may tip more or less about their respective axes to facilitate conformity of the plates to the contour ofthe .shoe. To provide for the application of more effective pressure by the plates to the shoe, there is further arranged above. each pair of plates a group of metal balls 466 resting on the upper plate and partially filling a recess-468 in the holder 439. Arranged in a series entirely around the group of balls are parallel vertical pins 416 which are slidingly movable in the holder 436 and rest at their lower ends on the upper plate 4 434, the pins being pressed downwardly by springs 412 which are mounted in sockets in the holder 430. It will be understood that the pins are near enough together to prevent escape of the metal balls and serve as a fence around the group of balls. When the shoe is pressed against the ironing plates the latter yield upwardly and are flexed to conform to the contour of the shoe, pressing the pins 410 upwardly until the balls 466, which adjust themselves in accordance with the contour of the shoe, completely fill the recesses 468 in the holders 430. The balls are then fixed relatively to the holders by the pressure against them and serve as positive means to prevent any further upward yield of the plates relatively to the holders, thus rendering the plates 1 over and in contact with a heater 414 whereby they are maintained in a heated condition. This heater is secured to a bar 416 (see also Fig. 4) having forwardly extending arms 418 pivotally mounted on pins 488 supported .by lugs 482 on the bracket I15. The heater is thus permitted'to swing upwardly and downwardly. Light springs 484 mounted under the forward ends of the arms 418 and supported by. the bracket I15 tend to swing the heater upwardly, and when the ironing means is swung rearwardly from its position over a shoe the ironing plates 434 engage the forward end portion of the heater and depress it somewhat against the resistance of these springs, after which the springs maintain the heater yieldingly in contact with the plates. Upward swinging movement of the heater is adjustably limited by a stop screw 485 carried by the bar 416 and arranged to engage the bracket I15. Within the heater 414 is an electrical heating unit 486, and fast on the bar 416 at the rear of the heater is a box 488 into which extend electrical conductors connected with the heating unit.

The operator swings the ironing device forwardly to its position over the shoe by the previously mentioned handle I58, its forward movement being limited by contact of a stop face 498 mounted on a rod 494 on the frame. As shown in Fig. 6, the block 492 is a substantially square block whichis eccentric to the rod 494 and is mounted .to turn around the rod so that different sides of it may be in positionto stop the forward movement of the ironing device and thus to vary the position of the device. A spring-pressed ball 496 carried by the block is arranged to enter any one of four depressions in the rod'494 to .maintain the block in adjusted position. Two bosses 498 (Figs. 1 and 2) on the frame are arranged to engage inner faces on the bars 486 to I assist in preventing any swinging of the bars laterally of the machine in the ironing operation. The ironing device is partially counterbalanced by torsion springs 598 which are coiled around the rock shaft- 292 and tend to swing the bars 496 forwardly, thus rendering it easier for the operator to swing the device into operative position.

When the ironing device is in its position over the fore'part of the shoe bottomtheoperatorforces previously described fluid pressure means provided for raising the shoe support. In order to render this fluid pressure means operative to raise the shoe support at this time, there is provided a 1o. bar 502 (Fig, '7) slidingly movable in a bearing in the frame and having an uptiu'ned forward end for manipulating it, this bar being connected at its rear end by a pin 504 to the bell-crank lever 3 which controls the valves in the valve unit 308. By pulling the bar 502 forwardly the operator may elevate the link 3I2, thereby causing the upper valve of the valve unit to open and the lower valve to close as will be readily understood from the previous description of these parts. The oil is thereupon forced into the cylinder 302 to raise the shoe support and cause the ironing means to act on the margin of the upper with an'inward wiping and pressing action as hereinbefore described. It will be understood that the forward movement of the bar 502 does not afl'ect the connections between the bell-crank lever 3I4- and the treadle, since the block 3I8 slides upwardly along the rod 320 withoutimparting any movement to this rod. The bar 502 is maintained in its forward position by a spring-pressed ball 506 in engagement with the bar in a groove 508 in the bar. This ball further cooperates with a groove 510 in the bar to maintain the latter in its normal-rearward position. The bar is not affected by the movement of the bell-crank lever 3! which results from depression of the treadle 200, because of the provision of a slot 5I2 therein along which the pin 504'is movable.

In the operation of the machine, the operator mounts a last and shoe on the'last pin I0 at that side of the machine which isappropriate for the particular shoe, whether aright or a left, the slide 62 which carries the heelpin being located at that time substantially at the forwardend of the bar 30.. It will be understood that thegieel pin and the toe rest will each have been pro erly adjusted by the means hereinbefore described in accordance with the requirements of the style and size of shoe, and that the shoe support holder 10 also will have been adjusted about its axis so that the bottom of the forepart of the shoewill lie substantially parallel to the bottom face of the holddown plate 82. After thus mounting the last and shoe on the last pin, the operatornmoves the slide 62 with the shoe toward the toe rest to the proper position indicated by the gage I32, the slide being thereafter locked against reverse movement by the detent 98. The, shoe is then in the position indicated by dotted lines in Figs. 2 and 6 with its forepart resting upon the lasting apron I16 supported by the toe rest pad I4. By depression of the hand lever I22 the operator next forces the hoe support upwardly through the action of the wedge I62 to press the bottom of the forepart of the shoe against the holddown plate 82. i

Thereafter the operator partially depresses the treadle 290, as a result of which the fluid pres sure means is rendered eifective to impart further upward movement to the shoe support and thus to .press the shoe more firmly against the holddown plate, and also to stretch the lasting apron I16 upwardly at the opposite sides of the shoe to conform the unlasted portion of the forepart of the upper to the contour of the last, the toe rest acting through the apron also to conform the upper to the last at the top of the forepart. While holding the treadle in its partially depressed position the operator then swings inwardly one of the levers 346 and locks it against reverse movement. By such movement of the lever the arm'342 thereon, to which the forward end of one of the cables 338 is connected, is carried inwardly over the shoe bottom to position the cable relatively to the tensioned lasting apron and to wrap it in a curve about that portion of the apron which is located at the beginning of the waist portion of the shoe. Next the operator further depresses the treadle 290 to pull downwardly therebyon the rear ends of the'two cables 338, as a result of which that cable which is effective on the lasting apron is drawn forcibly inward over the shoe bottom. In response to the pull of. the cable thereonthe arm 342 is swung farther inwardly and somewhat forwardly toward the toe end of the shoe. When the lasting apron'in this operation has been crowded or wedged by the cable somewhat inwardly between the shoe bottom and the abutment plate I34 so as to insure against loss of control of the upper, as indicated in Fig. 13, the force applied to the treadle becomes great enough to overcome the resistance of the springs 392, whereupon the upwardly extend-- ing arms of the bracket 318 at the rear end of the treadle swing forwardly and cause the fluid pressure means to release the lasting apron, so that the portions of the apron which are above the cables 338 are lowered, as indicated in Fig. 14. As further indicated in that figure, the cable which is acting on the apron ispulled farther inwardly over the shoe bottom as the upward pull on the apron is thus relieved, thus completing the laying of the margin of the upper over the insole into position to adhere to the insole, the pressure of the apron on the margin of the upper being increased by the deflecting action of the plate I34. At this stage in the operation the operator permits the treadle 290 to rise far enough to cause the bracket 318 to be swung back to its normal position by the springs 392, as a result of which the fluid pressure ,means is again rendered effective to pull upwardly on the lasting apron. The operator then unlocks the lever 346 which he had previously swung inwardly and returns it to its idle position, the cable being withdrawn from over the shoe bottom. Thereafter the same operations are performed by use of the cable 338 at the other side of the shoe, thus completing'the lasting of the forepart of the shoe. The operator then completely .releases the treadle 280, thus rendering the fluid pressure means no longer effective to pull upwardly on the lasting apron or to force the shoe support upwardly.

By lifting the hand lever I22 the operator next causes the shoe support to be lowered far enough to carry the shoe out of, engagement with the holddown plate 82. By means of the handle I50 he then swings the ironing means forwardly into action on the margin of the upper throughout the length of the forepart of. the shoe bottom the ironing plates 434 yielding upwardly, as illustrated in Fig. 19 and also conforming themselves to the contour of the shoe bottom. By such upward yield of the plates the groups of the two ironing units 1 move inwardly toward each other with a wiping balls 466 which overlie the plates are caused to.

flll the recesses 468 in the holders 430 and to become fixed relatively to the holders so as to serve as positive means to transmit pressure from the holders to the plates, the holders at the heat furthermore tends. to accelerate the setting of the cement'whereby the upper operated upon by the lasting means is secured to the insole. The inward wiping action of the ironing means on the margin of this portion of the upper further tendsto tighten the upper over the edge of the insole.

While the shoe is thus maintained under pressure of the ironing means the operator may perform the same operations described on another shoe by use ,of the other half of the twin m'achine, and after that shoe has been forced against the ironingmeans at that side of the machine he will release the, shoe previously operated upon by first moving the bar 502 rearwardly to render the fluid pressure means no longer eiiective on the shoe support and by then lifting the hand lever 122.. The ironing means first used will thenbe swung rearwardly to its idle position; carrying the ironing plates again into contact with the heater "4. It will be understood that-any danger of subjecting the shoe to excessive heat by too long a contact with the ironing means'is obviated by reason of the fact :that when the ironing means is in contact with the shoe it is removed from the source of heat.

The shoe 'shown in Fig. 20 to illustra the character of the work performed by the machine is one in which the toe. end of the upper is secured adhesively to the insole and in which they upper along the shank portion of the shoe is secured'by staples driven and anchored in the insole in the manner disclosed in Letters Patent No. 1,815,296, granted on July 21, 1931 upon an application o1 George Goddu; It is to be understood, however, that themachine is not limited to use on a shoe previously operated upon in that particular way.
